EDMONTON — NDP Leader Rachel Notley says Alberta’s Education minister won’t have credibility until he answer questions on why he favoured his riding with modular schools ahead of his own byelection race.

Gordon Dirks was under fire on the first day of the legislature session for his decision last month to deliver two modular classrooms to a school in the riding of Calgary-Elbow just days before voters made him the winner there in a tight race.

Calgary school officials had already identified six other schools that were higher priorities for the modulars.

Dirks has refused to say why he did it, except to say he’s trying to help wherever he can.

The opposition parties have asked the ethics commissioner to investigate.

Notley says until Dirks deals with the issue, Albertans can’t trust him to make decisions untainted by partisan political motives.
